For now I put profiler that I used to do tests here: http://kam.mff.cuni.cz/~ondra/strrchr_profile050813.tar.bz2 One thing you could help is that I place results to my page for now because I did not have time to find/setup suitable hosting and it would be good to have one. I modified a script that I use for automating connecting to various hosts in my department for wider usage. It will now automatically send me results to my email. A better way with hosting would be for example to have scponly/ssh accounts for commiters so pages can be updated directly (easily done by changing mutt command to scp one). To use it you need to copy profiler to directory ~/benchmark_string/strrchr_profile Then you need to fill file bench_list with machines to test, my file is like: bench ondra@foo.kam.mff.cuni.cz i7_nehalem bench ondra@bar.kam.mff.cuni.cz i7_sandy_bridge bench ondra@baz.kam.mff.cuni.cz i7_ivy_bridge After that run attached benchmarks_strrchr file.
